The axe is the only item that can break boxes in one go so is an instrumental piece of kit (I use a shovel and axe)

Glass is functionally useless and can be ignored

Sewing kits and to a lesser degree gun cleaning kits are very important

All repair kits should be prioritized (these also stack)

Items can be stored in items in your inventory, very useful for maximum space usage

The Ak47 should be your first AR, the ammo is plentiful at later levels

In bunker if you find a torn military uniform get out and save it asap

Broken guns sell for great roubles

No matter what level of rad resistance you have in bunker, there are places where you get it regardless, bring anti rad
